Chalcopyrite and Chrysoberyl Optic Character

Chalcopyrite and Chrysoberyl optical properties play a significant role while distinguishing these gemstones from each other. These properties are influenced by the Chalcopyrite and Chrysoberyl Physical Properties like crystallographic symmetry, pleochroism,etc. in the crystal. Some of the optical properties are refractive index, luster, optic character, pleochroism etc. Prominent among these is Chalcopyrite and Chrysoberyl optic character. You might have noticed your gemologist rotating the gemstone while testing it. Rotating a gemstone along its optic axis helps in determining its optic character. Chrysoberyl has Biaxial/+ character.

Chalcopyrite and Chrysoberyl Transparency

Similar to their colors, Chalcopyrite and Chrysoberyl transparency can also be used as criteria for their primary identification. Although transparency cannot be the only criteria for gemstone identification, it can efficiently used in gemstone grading. Talking about their transparency, Chalcopyrite is Handbook of mineralogy (2001) while Chalcopyrite is Handbook of mineralogy (2001) in appearance.
